I need to circulate money between exchanges automatically. I want to transfer cryptocurrency (BTC, LTC) between exchanges. I find that these exchanges have API calls for withdrawal options: Cryptsy, Poloniex, Bitstamp, Bittrex and Bleutrade.
Is there any other way to implement this for the exchanges which does not provide withdrawal options via API? I also want to transfer USD between exchanges. Can I implement it programmatically i.e via API?
